Selective laser spectroscopy of Mn4+-Mn4+ pair centers in SrTiO3 crystal

Original language description

Zero-phonon lines of a pair center of Mn4+ ions are observed in the luminescence and luminescence-excitation spectra of SrTiO3:Mn crystal. Based on the experimental data, the energy-level structure of the ground state |4 A 2g ,4 A 2g > and excited state|4 A 2g ,2 E g > of the Mn4+-Mn4+ pair center is constructed. It is shown that the exchange interaction in the ground state of the Mn4+-Mn4+ pair is antiferromagnetic. Energies of the levels are calculated assuming that the pair is formed by Mn4+ ions occupying neighboring octahedral positions of Ti4+ ions along the [110] axis. Experimental values of the exchange integral in the ground state |4 A 2g ,4 A 2g > and energies of spin multiplets in the excited state |4 A 2g ,2 E g > agree well with calculation of the exchange interaction carried out within the framework of the channel model with the parameters J ?? = 32 cm4-1 and J ?? = 45.5 cm4-1.
